WIRE-DRAWING DIE.

SPECIFICATION forming part of Letters Patent No.321,033, dated June 30,1885.

Application filed March 17, 185-3.

To all whom it may concern.-

Be it known that I, ELIAS M. JOHNSON, of the city, county, and State ofNew York, have invented a new and useful Improvement in VVire-Dies, ofwhich the following is a full, true, and exact description, referencebeing had to the accompanying drawings.

In making die-plates for drawing wire it has heretofore been customaryto drill a number of holes in such die-holder, so that as one holebecame toolarge the wire could be drawn through another hole, the diesbeing perma nent in the die-holder. By my improvement I am enabled toavoid, the destruction or remaking of the entire wireplate when theholes have become too large, and this I accomplish by fitting in thedie-holder a removable die, whereby when the hole in one die has becometoo large another may be readily substituted therefor.

My invention will be readily understood from the accompanying drawings,of which Figure 1 represents a plan view of my contrivance; Fig. 2 asection showing the plate in position; Fig. 3, the die-plate, and Fig. 4the equalizing elastic cushion.

My apparatus consists, generally, of a dieholder, A, in which is madeacavity or chamler, F, to receive the parts B, O, and D.

0 represents the die-plate, consisting of a solid block of steel havinga perforation through the center thereof, and preferably rests upon theelastic cushion D, thereby equalizing its position when the wire isdrawn.

B represents the tallow-cup, which serves,

likewise,to hold the plate 0 in position. This tallowcup is lockedin thechamber by screwclips E E.

(No model The operation is readily understood. The wire is drawn, asusual, through the die 0, and, if desired, the tallow or other lubricantmay be placed in the cup B.

I am aware that it has been proposed to make tools for drawingsoft-metal tubes with holders having conical openings, and conicalthimbles therein of metal so thin that the draw opening is greater indiameter than the thickness of the metal. Myinvention differs fromthisin having a block much thicker than the diameter of the opening, sothat there can be no possible springin the same, and in providing itwith a fiat side by making it rectan-. gular, so that it cannot be setout of true in the holder. I therefore do not claim, broadly, a holderhaving a socket for a detachable perforated piece; but

What I claim as my invention, and desire to secure by Letters Patent, is

l. The combination, in a wire-drawing tool, of a holder, A, having anopening formed, as set forth, to receive a rectangular steel blockfitting said opening, and having a central draw-orifice, substantiallyas set forth.

2. The combination of the die-holder A, die-plate O, and tallow-cup B,substantially as described.

3. The combination of the die-holder A, tallow-cup B, die-plate O, andelastic cushion D, snbstantiall y as described.
